BRIDLER, OF SAN FRANCISCO, CALIFOBNIA, ASSIGNOR OF ONE-HALF TO ALFRED HAMPTON, FRANK J, MILLER, AND FREDERICK HANSMANN WINDOW CONSTRUCTION Application filed July '14, 1928.

The present invention relates to improvemerits in window constructions and more particularly to improvements in double hung windows wherein the sashes are hinged in opposite side edges of the casement and adapted for free vertical movement therein and for horizontal inward swinging movement relative to each other for convenient cleaning of the window panes from the inside of the structure.

The present application embodies various improvements and refinements of detail over the constructions embodied in my Patent No. 1,575,811 issued March 9th, 1926, and Patent No. 1,603,741, issued October 19, 1926.

The primary object of the present invention is to provide an improved window of double hung type in which the sashes there of are slidably hinged in the easement in such manner that one or both sashes may be swung inwardly in a horizontal plane into the room to facilitate washing thereof.

Another object of the invention is to provide a double hung window in which the hinge and counter-weight construction and arrangement is greatly improved and simplified.

Additional to that of the foregoing objects is to provide a window of the class designated in which each sash is provided with a single counter-weight and weight cord, these cords being arranged to function inside the pulley stile and completely hidden from view.

Other objects and advantages of the invention will be apparent with reference to the subjoined specification and the accompanying two sheets of drawings, in which:

Figure 1 is a perspective view of my im proved window as it appears from the inside of a'room and with both sashes drawn down and swung inwardly for cleaning purposes;

Figure 2 is an elevation showing the window as it appears from the inside of a room with both sashes in closed and locked positions, portions of the casement being broken away to disclose the hinge and counter-balance weight arrangement;

hand pulley stile, the View being indicated by the line 33, in Figure 2;

Figure 4isatransverse sectional view taken just above the upper sash and shows the relative positions of the upper and lower sashes and their hinge and counter-weight arrangement, the view being indicated by the lines 4-4, in Figures 2 and 3:

Figure 5 is an enlarged horizontal sectiona1 detail of one of the lower sash hinges and guide slot for the same, the section being indicated by the line 5-5, in Figure 2;

igure 6 is a perspective detail of the up per portion of the low r hinge for the upper sash;

Figure 7 is a perspective detail of the remaining. or butt portion, of the hinge shown in Figure 6, these being adapted for separation when the upper sash is in closed position and for engagement when in lowermost position;

Figure Sis a plan detail, showing the angular arrangement of the pulleys relative to the pulley stile, so that the weights may clear the stiles when moved vertically; and

Figure 9 is a face view of the removable molding strip which is provided with snaps of glove character to facilitate its removal when it is desired to swing the sashes into the room.

Referring to the drawings in detail, in which the preferred embodiment of my invention is illustrated, the numeral 10 designates the usual form of window casement, including pulley stiles 11 and 12, sill 13, of usual construction, and the upper and lower sash members 14 and 15.

The stiles 11 and 12 are longitudinally slotted, as indicated at 16 and 17, the slot 17 extending substantially throughout the full length of the stile 12, while the slot 16 extends downwarlly in the stile 11 a distance substantially equalling one-half its length, as shown in Figures 2 and 4.

The lower sash 15 comprises a single glass pane 18 having a side frame 19 provided with a pair of spaced hinge members 20 and 21 embodying tongues 22 and 23 adapted to extend through the stile slot 17 and arranged for sliding movement therein, said tongues being and slotted, as indicated at 26, in Figures 3 and 5, to receive the hinge tongues, upon which they are maintained by keys, or the like, 27.

The hinges 20 and 21, as thus arranged, permit the lower sash to slide freely between the pulley stiles 11 and 12 and to swing outwardly in a horizontal plane when in lowermost position, by the removal of the parting strip 28, which strip is held in place in the easement in any suitable manner, such as by means of snap fasteners 29, as shown in Figure 9.

The upper hinge tongue 22 of the hinge 20 is secured to a single counter-weight 30, of usual form by means of a cord 31, which passes over anangularly disposed pulley 32 secured in position against the pulley stile 12 and arranged directly over the tongue 22, as shown in Figures 2, 3 and 8. In this manner, the lower sash is efi'ectively balanced and slides up or down smoothly in the casement, or swings inwardly, as hereinbefore described.

The upper sash 14 is centrally hinged, as indicated at 33, and comprises two panels 34 and 35 having a fastener 36 of suitable form to hold the panels 34 and 35 normally aligned. This sash is provided with an upper hinge 37 having a tongue 38, which projects through the short slot 16 in the stile 11, and bears a shoe 38 and is exactly like the hinges 20 and 21 of the lower sash, except in that its offset 39 is reversely arranged relative to the offsets of said hinges, as clearly shown in Figure 4, the tongue 38 of said hinge being connected to a counter-weight40 by means of a cord 41'which passes over a pulley 42, as shown in Figure 2.

A hinge butt 43 is fixed on the stile 11 contiguous to the parting strip 44, Figures 2,6 and 7, and just above the sill 13,. as clearly shown in Figure 2, and the curled section 45 thereof, Figure 7, is opened slightly and adapted to receive the pintle 46 of the hinge 47, Figure 6, carried by the lower end of the upper sash when said sash is pulled down until the two hinge sections interlock,

or to a point where the pintle 46 engages the,

curled section 45 of the member 43.

In operation, my improved window functions as follows:

3 Either upper or lower sash may be thrust up or down in the usual manner by releasing the usual lock 48, but, if it is desired to swing the sashes into the room for cleaning, or other purposes, the moulding strip 28 is removed, which releases the free edge of the lower sash, it, of course, being first raised sufliciently to clear the sill 13, whereupon it may be readily swung into the room, as indicated in Figure 1.

If it is desired to also swing the upper sash 14 inwardly, this is accomplished by releasingthe fastener 36 and drawing the upper sash down until the hinge pintle 46 interlocks with the curled portion 45 of the hinge butt 43, at which point the free end of said upper sash may be swung into the room, by virtue of its breaking at the hinge points 33 of the panels 34 and- 35, thus allowing its free edge to clear the parting strip 49 which is mounted in the stile 12, as clearly shown in Figures 1 and 4.

Having thus described my invention, I claim and desire to secure by Letters Patent:

1. Window construction of the class described comprising, in combination, a casement embodying slotted pulley stiles, an up per and a lower counter-balanced sash mounted between said pulley stiles and adapted for slidable movement therebetween, a single sash cord for each sash, said lower sash consisting of a single panel and said upper sash consisting of centrally hinged panels, hinge members borne by said sash members and having tongues slidable in the stile slots, the upper hinge-tongue of each sash being connected to one of saidsash cords and a removable molding strip carried by one of said stiles providing, when removed, a clearance opening through which the sashes may be swung in a horizontal plane when in lowered positions.

2. In a window of the class described, the combination with a casement having slotted pulley stiles, of, upper and lower counter-balanced sashes, a single sash cord for each sash, hinge members borne by said sashes having tongues adapted for slidable movement in said slots, the upper hinge tongue of each sash being connected to one of said sash cords and guide shoes carried by said hinge tongues to maintain the hinges in slidable relation with said pulley stiles.

3. In a window of the class described, the combination with a casement having slotted pulley stiles, a pair of slidable and swingable sashes, hinge members carried by said sashes having tongues projecting through said slotted stiles, and a single counter-weight for each sash having a sash cord secured to the tongue of the upper hinge thereof inside the pulley stiles.

In testimony whereof I hereunto aifix my signature.

JOHN J. BRIDLER.
